There are only 2 species of flowering plants, grasses (mosses, lichens, liverworts and fungi included) and algae (snow algae). With the increasing temperatures these plants may successfully make it in antarctica, potentially meaning they may outcompete native plants for resources and food.

With this lowered carbon availability, the moss can’t be as selective, and it ends up with more 13C than it would otherwise. Part of the reason for this shift is that it has started raining in the summer. There are long periods of time during the year when it’s too cold for this to occur—the number of days of melt vary between 20 and 105 per year.

There are only two vascular plants that grow in Antarctica and these are found only on the coastal region of the Antarctic Peninsula. Plants can sometimes belong to weird scientific families. Furthermore, the particular enzyme in plants (RuBisCO) responsible for carbon fixation during photosynthesis has a preference for a particular type of carbon—it is more efficient to incorporate the lighter 12C isotope rather than the heavier 13C isotope. Instead it prefers secluded areas next to mosses and inside crevices. In other locations, where there are animals, it's possible that this botany is on the menu for all herbivores. The carbon from the carbon dioxide that mosses take in from the atmosphere to use for photosynthesis becomes fixed in the cells of the new growth. It doesn’t rain in continental Antarctica, so water is available only when snow and ice melt. The other is Antarctic pearlwort ( Colobanthus quitensis ), an herb. For starters, like all plants, mosses need water to survive. When young they have folded leaf blades then develop into long, dark green, erect stems.
